The BR/EDR ACL logical transport is used with either an ACL-C logical link for control data or an ACL-U logical link for user data and it is based on a BR/EDR Active Physical Link and either the BR/EDR Basic Piconet Physical Channel or the BR/EDR Adapted Piconet Physical Channel. See Figure 2.
Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.
In retransmission and flow control modes, L2CAP can be configured for reliable or asynchronous data per channel by performing retransmissions and CRC checks. Reliability in either of these modes is optionally and/or additionally guaranteed by the lower layer Bluetooth BDR/EDR air interface by configuring the number of retransmissions and flush ...
The actual maximum code rate allowed depends on the error-correcting code used, and may be lower. This is because Shannon's proof was only of existential nature, and did not show how to construct codes that are both optimal and have efficient encoding and decoding algorithms.

The channel access control mechanism relies on a physical layer multiplex scheme. The most widespread multiple access method is the contention-based CSMA/CD used in Ethernet networks. This mechanism is only utilized within a network collision domain, for example, an Ethernet bus network or a hub-based star topology network.
Pits and lands are the depressions (0.12 μm deep) and flat segments constituting the binary data along the track (0.6 μm width). [8] The CD process can be abstracted as a sequence of the following sub-processes: Channel encoding of source of signals
